Most of my posts to date pertained to classic strikes familiar to everybody. In addition to those, there is a category of strikes in Systema referred to as strikes "with a twist", "change of direction", or "wandering" strikes. To deliver one of those, the striker turns the fist upon contact with the target so that the strike "screws" into opponent's body along a curve rather than a straight line, just like a screw into wood.

One really confusing thing to me in Systema was the concept of pushing or striking somebody with a fist without tension in the arm, chest, or shoulder. And understandably so - we are conditioned to believe that strong muscles equal more power, and the more muscular you are, the harder you can strike.

One interesting aspect of Systema is cooperative work. In theory, help from others should improve your chances of achieving a set objective, especially in combat. However, in practice this really depends on the situation and how well you are able to cooperate with the friendlies.
